I've been seeing graphical corruption whenever I try to play Diablo 3. The screen freezes for a minute, then all the graphics glitch out. It looks like all the textures and polygons are out of place, though I can still click on options if I can find them. Also, I get occasional stuttering while surfing the internet and in other apps. I have listed CPU/GPU temps below and my system setup. Also, I have tried opening the case and running a desk fan on the GPU, which didn't make much of a difference. Any help you can give would be appreciated!

The GPU temps are normal... And if GPU starts overheating - it should simply "throttle down" its own clock speeds without producing visual artifacts... Check the GPU fan: is it rotating full speed? If yes - then it's highly unlikely it is overheating. Also, make sure you have the latest official video drivers installed. Try checking other games (if you don't have any - download free game demos from Steam or somewhere else), or running benchmarks like the free "FurMark". If you'll get similar visual corruption with all of them and you have the latest drivers and the GPU fan is working - then your GPU or video RAM is most likely bad and you probably need a new card.
